Traveling Salesman Problem

This book is a collection of current research in the application of evolutionary algorithms and other optimal algorithms to solving the TSP problem. It brings together researchers with applications in Artificial Immune Systems, Genetic Algorithms, Neural Networks and Differential Evolution Algorithm. Hybrid systems, like Fuzzy Maps, Chaotic Maps and Parallelized TSP are also presented. Most importantly, this book presents both theoretical as well as practical applications of TSP, which will be a vital tool for researchers and graduate entry students in the field of applied Mathematics, Computing Science and Engineering

A comparison of statistical machine learning methods in heartbeat detection and classification

In health care, patients with heart problems require quick responsiveness in a clinical setting or in the operating theatre. Towards that end, automated classification of heartbeats is vital as some heartbeat irregularities are time consuming to detect. Therefore, analysis of electro-cardiogram (ECG) signals is an active area of research. The methods proposed in the literature depend on the structure of a heartbeat cycle. In this paper, we use interval and amplitude based features together with a few samples from the ECG signal as a feature vector. We studied a variety of classification algorithms focused especially on a type of arrhythmia known as the ventricular ectopic fibrillation (VEB). We compare the performance of the classifiers against algorithms proposed in the literature and make recommendations regarding features, sampling rate, and choice of the classifier to apply in a real-time clinical setting. The extensive study is based on the MIT-BIH arrhythmia database. Our main contribution is the evaluation of existing classifiers over a range sampling rates, recommendation of a detection methodology to employ in a practical setting, and extend the notion of a mixture of experts to a larger class of algorithms

The European Space: Borders and Issues

Beyond the establishment of the European Union, in a context where nationalism of the nineteenth century continues to have real success in the twentieth century, debates about the historical past and the future of this important actor on the international scene are always present in the current political environment and the European academia and beyond. The analysis on the character of the EU, the essence of the European integration process, the many types of internal and external borders are in a constant change under the impact of numerous factors of influence of all kinds, and this is the very topic of this volume. Not coincidentally chosen by the editors, this volume titled The European Space. Borders and Issues brings together a collection of articles and studies that combine, for a scientific purpose, the authors’ concerns regarding the exceptional scientific work of Professor Ioan Horga. Complex analyzes of the European space are crowned by an overview of European realities, the capacity to see beyond the historical realities of European prospects. It took into account the historical perspective on European space, whether it was bent on present realities, Professor Ioan Horga vocation is leading the research, the ability to see both the general and the particular. Either that he has taken into account the historical perspective on the European space or he has been preoccupied with the present realities, Professor Ioan Horga’s vocation is leading the research, the ability to see both the general and the particular

Planning Cities in Africa

This open access book provides insights into challenges, threats and opportunities of urban development in Africa. It discusses how and why African cities need localised urban planning concepts and theories to deal with challenges and threats of rapid urbanisation and climate change. The book delivers an in-depth view of the nature and gaps of the framework on which current planning practice and education in Africa are based. With that, it discusses the potentials of African cities to mobilise local knowledge, resources and capacity building for sustained and resilient urban growth. This work is addressed to educationists and practitioners in the field of urban development management, climate change adaptation and urban resilience. Specifically, such audiences include researchers, spatial planners, graduate students and member of civil societies working on urban development management
